Hi，all
I use CCD camera to capture real-time imaging to display on LCD,but it doesn't display for full screen.
as the picture,the red rectangle is the display area.The resolution of LCD is 1440x240,
display code：
static int init_vid0_device(int fd, struct fb_var_screeninfo *var_info)
{
vpbe_window_position_t pos;
printf("enter init_vid0_device()\n");
if (ioctl(fd, FBIOGET_FSCREENINFO, &vid0_fixInfo) < 0) {
printf("\nFailed FBIOGET_FSCREENINFO vid0");
return FAILURE;
}
/* Get Existing var_screeninfo for vid0 window */
if (ioctl(fd, FBIOGET_VSCREENINFO, var_info) < 0) {
printf("\nFailed FBIOGET_VSCREENINFO");
return FAILURE;
}
prev_vid0_var = *var_info;
/* Modify the resolution and bpp as required */
var_info->xres = test_data.vid0_width;
var_info->yres = test_data.vid0_height;
var_info->bits_per_pixel = test_data.vid0_bpp;
var_info->vmode = test_data.vid0_vmode;
var_info->xres_virtual = 1440;
var_info->yres_virtual = var_info->yres * VIDEO_NUM_BUFS;
.....
initialize_capture();
test_data.vid0_width = 1440;
test_data.vid0_bpp = 16;
test_data.vid0_xpos = 0;
test_data.vid0_ypos = 0;
test_data.vid0_vmode = FB_VMODE_NONINTERLACED;
test_data.osd0_bpp = 16;
test_data.osd0_xpos = 0;
test_data.osd0_ypos = 0;
test_data.osd0_width = 16;
test_data.osd0_height = 16;
test_data.osd0_vmode = FB_VMODE_NONINTERLACED;
test_data.osd0_coloridx = BLUE_COLOR;
strcpy(test_data.display_interface, "LCD");
....
bootarg:
setenv bootargs mem=80M console=ttyS0,115200n8 noinitrd rw ip=192.168.245.111:255.255.255.0:192.168.245.1 root=/dev/nfs nfsroot=192.168.245.122:/opt/nfs video=davincifb:vid0=1440x240x16,4050K@0,0:osd0=1440x240x16,1350K@0,0 davinci_enc_mngr.ch0_output=LCD davinci_enc_mngr.ch0_mode=1440x240 dm365_imp.oper_mode=1 davinci_capture.device_type=4
what's the problem?
